Wgat are they like on booking times? Only been there once before ages ago and seem to recall they weren’t overly fussed on times. Any advances on that with some more recent info?
Go there pretty regular and they are pretty strict on booking times. Last time I was there the guy in front of me was having a bit of a barney with the security lad. He’d turned up an hour early and been told to spin out and come back later.
Sorry just noticed the time that you posted!! Probably a waste of time now.
I had a job with the agency about this time last year going there every day with a container and it was pretty much the usual 30 minutes either way thing.
To counteract that there was some pretty nice eye candy working in the goods-in office. 
Was in two hours early for one consignment and six hours early for the other and back out again, tipped, signed and away in 15 mins. Then again we’re (my company not me) in there daily and its often a few pallets rather than bulk load.
Then got into Ocado over the road early after, and was out of there in 15ins too 
None of it really mattered, still had a collection in Atherstone but it meant I could have a longer kip!
